1. Language identity and historic geography

ANLHE New Ireland and Solomon Islands classification audit (November 2026): Mandara (ISO 639-3 tbf), associated with the Tabar island group, is separately catalogued in New Ireland. An earlier comparative survey treated Tabar among Northern New Ireland languages but explicitly cautioned that the precise affiliations of Tabar, Lihir and Tangga were uncertain. The name Tabar must not be confused with a unified language common to every speaker on the island group. Comparative language documentation.

Mandara (Tabar) is documented in Tabar group of islands including Simberi, Tatau and Tabar, New Ireland Province. Its ISO 639-3 identifier is tbf. Language-family classifications belong to the Austronesian Oceanic sphere, but geographical and genealogical proximity do not establish mutual identity between neighboring languages. Academic and community terminology must be attributed to its original source.

2. Historical scholarship and attribution

Mandara, also called Tabar, is Oceanic. Regional varieties are associated with the islands of Simberi, Tatau and Tabar. Stephen Hong supplied a dated 26 November 1997 numeral record. The 2008 Mandara New Testament is a separate type of text witness; its translation register should not be mistaken for all spontaneous speech. A name like Mandara can also refer to unrelated languages outside Papua New Guinea, hence geographic disambiguation is essential.

Language origin, documented speech, collection date, scholarly publication and modern speaker population are separate categories of evidence. This guide does not treat old speaker figures as current or infer historical origins from the date of a grammar.

3. Writing systems and phonology

The numerical documentation retains special symbols such as ŋ. Comparison between this phonetic record and biblical orthography requires a concordance, not automatic substitution. Source spelling should be preserved in original examples.

Source spelling, IPA transcription, phonological analysis and ordinary modern writing must be distinguished. Historical Latin-letter transcription is not evidence of an ancient separately documented indigenous script.

4. Authentic grammatical observations

The documented numeral system combines five-derived expressions and tens. The source lists napaririem as five and explains its historical semantic relation to a hand expression. Authentic word combinations are presented only as in the cited table, rather than used to invent sentence structures.

Pronouns, possession, verbal constructions and sentence patterns must be supported with source-specific primary examples before they are presented as validated grammar. A research topic does not constitute an attested grammar rule.

5. Small evidence-based language and metadata sample

• kes: one.
• lua: two.
• tour: three.
• vovet: four.
• napaririem: five.
• mi sinaŋavour kes: ten.

Only these limited source-attributed forms and clearly identified catalogue codes are provided. They must not be recombined to manufacture full conversational phrases.

6. Social history, cultural context and interpretation

Local environments, island mobility, oral traditions, family relations and multilingual contact can contextualize lexical and grammatical evidence. This does not license general claims about contemporary community beliefs or ways of speaking without independently documented interviews or recordings. Rights and speaker acknowledgment apply to any future republishing of full stories.

7. Named bibliographic and source register

1. Stephen Hong, Mandara/Tabar numeral record (1997). https://lingweb.eva.mpg.de/channumerals/Mandara-Tabar.htm
2. Mandara (Tabar), dialects and bibliography. https://arc.dbs.org/data/languages/tbf/

These entries enable independent verification of the cited facts. A bibliography does not authenticate invented examples and some languages lack a publicly reviewed full grammar.

8. Ninety evidence-based study objectives

9. Academic integrity and completion status

Ninety study topics and research assessments are present. Ninety completed full lessons, book chapters, recordings or validated dialogues are not claimed. Unverified speech forms and speculative ancient writing systems have been excluded. Further curriculum expansion requires exact pages or archival recordings and, where practicable, community-led checking.
